Answer this question truthfully
### Question: What causes Upper gastrointestinal bleeding?
### Response: The most common cause of upper GI bleeding is an ulcer in the stomach or small intestine. Irritation of the stomach or esophagus can also cause an upper GI bleed. A group of medicines called nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and naproxen, are common causes of stomach and esophagus irritation. *Another common cause of bleeding is liver disease from chronic alcohol use. Sometimes the esophagus bleeds because it is torn after forceful coughing or vomiting.
